First solar powered transcontinental flight

Pilot completes first solar-powered transcontinental flight from Madrid to Rabat THE AUSTRALIAN, AP June 06, 2012 AN experimental solar-powered plane has landed in Morocco’s capital after a 20-hour trip from Madrid in the first transcontinental journey by a craft of its type.

With the wing span of a Boeing 777, the plane appeared out of the pitch darkness over the runway, suddenly turning on its lights and gliding to a landing in Rabat, its four propellers already still. “It was perhaps the most beautiful flight of my life,” said pilot
Bertrand Piccard, who has already circumnavigated the world by balloon.
“I have dreamed since I was a child of flying without using fuel.”

The single-seat aircraft is fitted with 12,000 solar cells across its immense wings and but only weighs just as much as the average family car, according to organisers.  The plane is the first of its kind to fly both during the night and day as the solar panels charge the batteries for night flying….. http://www.theaustralian.com.au/news/world/pilot-completes-first-solar-powered-transcontinental-flight-from-madrid-to-rabat/story-e6frg6so-1226386003212

Solar panel that follows the sun

includes video  Heliowatcher allows solar panels to track the sun  http://www.earthtechling.com/2012/06/heliowatcher-allows-solar-panels-to-track-the-sun/   4 June 12, They’re called solar panels for a reason: they need the sun in order to generate electricity. Whether we’re talking about pocket-sized, portable solar chargers or massive rooftop arrays, direct sunlight is the must-have ingredient on which all other elements of solar-energy production depends.

You might think that simply placing solar panels on a rooftop or balcony free from shade would be enough. Except there’s that small matter of Earth rotating on its axis. So throughout the day, the sun moves across the sky, cutting into the efficiency of fixed panels. But what if the panels could automatically change their position to follow the sun and enjoy an uninterrupted flow of direct sunlight? Two electrical engineering students at Cornell are currently testing just such a technology, and it looks promising.

Solar panel that follows the sun

As this review points out , HelioWatcher’s design is simple and effective: “The base is mounted like a Lazy Susan, able to pivot on the horizontal plane. The bottom edge of the solar panel is mounted with two door hinges, with a motorized screw jack used to raise and lower it.” Using a GPS module and magnetometer, the HelioWatcher  allows the user to place the system anywhere in the world without any calibration. The HelioWatcher then calculates what the sun’s current location is and orients the panel to the appropriate angle. It also utilizes a quadrature of light-detecting diodes to correct for short-term light obstruction, such as clouds or shade.

This system is a vast improvement over other solar tracking systems that adjust position based on either a predetermined algorithm or light detection. Instead HelioWatcher combines elements of both technologies to leverage the guaranteed accuracy of a geospatial algorithm while also correcting for local or short-term changes, such as cloud cover or shade. Here’s a video, prepared by the two students, that explains the system:

Ways to make renewable energy competitive in USA

Two financial mechanisms that have driven investment in traditional energy projects — real estate investment trusts and master limited partnerships — could, with some help from Washington, be extended to renewable energy projects to lower their cost and make America’s energy future cleaner, cheaper — and more democratic

How to Make Renewable Energy Competitive, NYT By FELIX MORMANN and DAN REICHER June 1, 2012 STANFORD, Calif.Renewable energy needs help. Technological innovation has significantly reduced the cost of solar panels, wind turbines and other equipment, but renewable energy still needs serious subsidies to compete with conventional energy. Today, help comes mostly in the form of federal tax breaks.

These tax incentives, and the Congressional battle over extending them for wind projects beyond the end of this year, mean that other, more powerful policies to promote renewables are not getting the attention they deserve. If renewable energy is going to become fully competitive and a significant source of energy in the United States, then further technological innovation must be accompanied by financial innovation so that clean energy sources gain access to the same low-cost capital that traditional energy sources like coal and natural gas enjoy.

Mainstream media waking up to Fukushima danger, and Germany’s renewables leadership

The second energy event of this past weekend was uplifting and extraordinary, due to an extremely sunny weekend, half of Germany’s electricity was generated by solar power two days. The decision to close down and eventually shut all of Germany’s nuclear reactors now appears to have been justified

Germany’s Solar Success and Fukushima’s Crisis: Intelligent Energy Priorities, HUFFINGTONPOST, Vivian Norris   06/01/2012 Last weekend, events took place which should make us think about the future of energy on this planet. Firstly, radioactive bluefish tuna was caught off the coast of California. The radioactivity, though in fairly small amounts, could be directly traced to the releases from the disasters at the reactors at Fukushima Daichi, following the devastating earthquake and tsunami.

And more importantly, the public finally received some answers from those supposedly in charge in Japan during the accident. Former Prime Minister Kan testified that the ties between regulators and TEPCO was so intertwined, and the accident so profound, that he called for Japan to stop all use of nuclear energy. For once, it appeared that mainstream media paid attention and published both Kan’s words, as well as articles on serious concerns about the status of fuel pools at Fukushima. Experts and more fringe elements on the internet had been publishing good information for over a year. It is to the New York Times’ credit that they acknowledged the role that the pressure from these groups played in forcing TEPCO and the Japanese government to admit they had not been forthcoming.

Solar smart grid a Middle East first for Bahrain

Bahrain Commits to Green Energy, Sacramento Bee, By Kingdom of Bahrain, Jun. 1, 2012 –  MANAMA, Bahrain, — /PRNewswire-USNewswire/ –– In one of the first major solar energy projects in the Middle East, Bahrain yesterday announced plans to implement a solar smart grid in Awali, paving the way for future smart cities in Gulf.

“The Middle East has for some time evaluated the integration of solar energy for reduction
of reliance on non-renewable energy sources. However, Bahrain is among the first in the region to implement a project of this kind, demonstrating a serious commitment to long term solutions,” Marty Youssefiani, CEO of Caspian Energy Holdings, said.

Bahrain’s National Oil and Gas Authority (NOGA) is implementing five megawatt solar
capacity into a wireless smart grid network in cooperation with Petra Solar, Bahrain Petroleum Company (BAPCO) and  Caspian Energy Holdings.

The grid circumvents common interconnection issues and costs of traditional solar systems because of its ability to install into the current transmission and distribution infrastructure. Bahrain intends to spread similar sustainable technology across the country in the future…… http://www.sacbee.com/2012/06/01/4531560/bahrain-commits-to-green-energy.html#storylink=cpy

Germany’s dazzling success with small scale solar energy

the really meaningful story starts with a different number: 189.24 GWh. That’s the amount of electrical energy generated from more than a million PV solar systems spread all over the country on that record day. Not only was this almost 14% of Friday’s total electricity consumption in Germany, it was also, actually, not that unusual.

For the last couple of weeks, the output of PV solar peaked within an inch of the 20 GW line several times, and it never peaked very low throughout the month. The lowest peak load was 8 GW, while the average peak load of PV solar was 16 GW. So, it seems that solar is not as unreliable as conventional wisdom and media outlets often lead people to believe. Because I can tell you that we didn’t have 4 weeks straight of sunshine here in Germany, that’s for sure.

In-Depth: Germany’s 22 GW Solar Energy Record Clean Technica, MAY 31, 2012 BY THOMAS Last Friday, on the 25th of May 2012, Germany set a new world solar energy record in photovoltaic solar energy: 22.4 GW of photovoltaic energy on the grid covering over 30% of all energy demand! That’s the equivalent of 20 huge conventional fossil or nuclear power plants. This is clearly amazing news that made headlines around the world and was accompanied by either praise or the typical anti-solar bickering that is rather dominant in big media outlets even today (or especially today).

The latter didn’t mind even using this incredible clean energy accomplishment to repeat the usual ignorant talking points, disinformation, or flat out lies. Unfortunately, those news pieces and early articles praising the event didn’t fully exploit the opportunity to explain the true significance of having so much solar energy in the energy mix, especially when looking at the technological developments and opportunities of the coming years.

Distributed solar energy, and distributed energy storage

In-Depth: Germany’s 22 GW Solar Energy Record Clean Technica, MAY 31, 2012 BY THOMAS“…….Millions of Batteries in Buildings — Utopian? …… it is very easy to show that it’s just a matter of time until the combination of energy storage for homes with rooftop solar energy and/or small-wind becomes viable and even profitable.

Today, there are still about 6.4 million oil tanks in homes and buildings all over Germany storing energy in the form heating oil. Installing such a tank costs several thousand Euros today. So, why shouldn’t independent power producers start putting up new forms of energy storage in the same numbers as soon as it makes economic sense?

How would 6 million home storage systems change the energy system? Well, 6 million 10 kW / 25 kWh would mean a distributed storage system with 60 GW maximum output/input and 150 GWh of capacity. That’s already enough storage for 10% of the current daily consumption, more than enough to power all German households through the night. It’s also coming a long way to fill the gap between renewable baseload power (hydro and biomass) and variable sources like wind and solar.

That 10-kW/25-kWh battery is not fiction by the way. It’s quite similar to the battery pack that powers the Nissan Leaf right now, Just one battery that will soon reach production volumes in the hundreds of thousands as factories in Japan, Europe, and the US crank up production by 2013.

It’s true that the $15,000 price tag for the battery is too high right now. But, since all kinds of competitors are investing in this market, economics of scale, innovation and optimization will certainly reduce the cost of such batteries in the coming years. In the case of multi-kWh batteries, this development is a lot more obvious than what happened with the price for solar cells just 7 years ago. The fall of prices surprised many analysts back then. Today, prices for solar cells are 70%-80% cheaper than what they were in 2007, putting the cost of solar systems well below $2 per Watt in Germany…. .. https://mail.google.com/mail/u/0/?shva=1#inbox/137a6ed1432cd545

Germany doing well with nuclear phaseout – despite the nuclear lobby’s lies about this

Busting the carbon and cost myths of Germany’s nuclear exit, Guardian UK  Damian Carrington, 23 May 12  Critics of the atomic phase-out said energy emissions, costs and imports would all rise. They were wrong.  it’s worth taking a look at what actually happens when you phase out nuclear power in a large, industrial nation.

That is what Germany chose to do after the Fukushima nuclear disaster, closing eight plants immediately – 7GW – and another nine by 2022. The shrillest critics predicted blackouts, which was always daft and did not happen.

But more serious critics worried that the three things at the heart of th eenergy and climate change debate – carbon, cost and security of supply – would all head in the wrong direction. Here in Berlin, I have found they were wrong on every count. Continue reading →

The transition to renewable s – American’s energy revolution under way

America’s renewables revolution, Climate Spectator , 24 May 2012 John Kemp  “……Speaking in his state of the union address to Congress in January, the president claimed, “We’ve subsidised oil companies for a century. That’s long enough. It’s time to end the taxpayer giveaways to an industry that rarely has been more profitable and double-down on a clean energy industry that never has been more promising.”

But the rhetoric obscures an unprecedented push to cut energy consumption  and increase the share of renewable energy generation underway at all levels of government as well as in the private sector.
Federal, state and local governments, coupled with local power and gas utilities, are pouring billions of dollars a year into a vast range of initiatives to boost efficiency and renewables.
Support for efficiency and renewables is split across thousands of
different programs, which has tended to hide the scale of the overall effort. As a result, many energy analysts fail to appreciate the scale of the shift underway. However, the sheer amount of support being given to clean technology and energy efficiency programs suggests a revolutionary transformation of the energy system will likely occur in the next two decades.
